Hi All! New to chickens and just ordered our first flock. While we wait for them to hatch I'm eagerly reading up and educating myself on as much as I can. I wanted to run a potential plan by you all and get some feedback. I have about an acre of land in MD and think a tractor coop might be best suited for our backyard. While I anticipate plenty of supervised free ranging during the week, the majority of their time will be in the coop and run. So I want to have a larger size build for them. I'd like to move the building around my yard but am thinking maybe my plans for the build will make it too large to be feasible and wanted to brainstorm on here a bit first. This is the outline of a coop I am thinking of copying: http://steamykitchen.com/20640-the-palace-chicken-coop.html I an thinking of modifying it to use 1/4" hardware cloth. Also only doing the roof on top of the coop with 12" overhang and not over the whole thing, this is to hopefully save some weight and give more sunlight in the run. I would use hardware cloth over top of the run instead. Probably also sub out 2x4's in the run area since it wouldn't need to support the roof as those plans have it. I realize it is going to be HEAVY. I'm just not sure if it will be too heavy since most tractors I see don't look to be as big. I put together a monster playset with clubhouse and crows nest so I'm trying to get an idea on if it might work or not with that kind of weight. I was thinking a 3-4 wheel system of trailer jack wheels like this one here: http://www.etrailer.com/Trailer-Jack/etrailer/MJ-1206B.html Or maybe something similar with better wheels. I also liked this system: Just don't want to end up like this one: But also think I would be going for a better wheel system as well as the placement on his wheels are bad and should be closer to the back IMO. I also have a riding mower that I could use to move it if sheer brute force alone wouldn't work. Concerns: 1. It just does not work, wheels sink into yard too much to be feasible and be moved. 2. It does work but is such a pain in the *** I just never actually move the thing and probably end up keeping it in one spot anyway. 3. Decreased predator protection. I'm worried if I don't get it absolutely perfectly flat it might weaken the defense and allow predators to dig under the run and get the chickens. I have woods on three sides of my property and we have probably everything but bears/cougars around. 4. Chickens absolutely destroy the yard in the few days they are at each location and I just end up keeping them one place anyway. I'm thinking of a tractor instead of a dug foundation so that the chickens can help with bugs and get that in their diet (but still be safe) help aerate the yard and "fertilize" it. Also the main location I'd like to keep them in is the back half of the yard but during the wet season to help with moisture avoidance it would be good to move them closer to the house where our slope does not drain to. Also if it's a more heavy winter move them closer to the house so they are easier to get to etc. Anyway these are just some ideas in my head. I have a few months to get ready but would rather not waste money on something that has no way of working. I look forward to constructive feedback. I am very new to all this but want to learn. Thanks so much!
